can this work for Rk3168 devices? i have dumps-by-partition of my device and would probably require to use my own kernel.img, and some modules,lib patching but im willing to test.

also, how to change filesize of system.img? since my rom is set for 768mb.. can i just edit the parameter file to reflect the filesize or system.img that this rom has?

thanks.
[Miscellaneous Android Development] wuith:
Hi Oma, I have another question. The minimum brightness level with CM11 for RK3188 is too low for my RK3066 tablet and if I low too much the brightness level I just get black screen. With Xposed Framework & Gravitybox I can configure that minimum level to avoid this. However the Gravitybox makes the rom not so stable (CM & Xposed...)... Is there another way to configure the minimum brightness level (build.prop, etc)? I have seen that at sys/class/backlight/rk28.bl/max_brigthness I could configure the maximum level but I see nowhere the minimum.

Thank you!

does anyone else has a discolored screen using AOSP 3.4 build for 3066 ??
[Miscellaneous Android Development] ildar_prophet:
is the screen "discolored" in the bootloader (the 1st image you see on power on) ? Then it shouldn't be a ROM problem, but hardware's.

If the bootsplash is fine then check your kernel: it may not fit your tablet. You should find another kernel.
[Miscellaneous Android Development] Greyjawripper:
No I have a discolored screen even when I boot into the OS.... Its weird cause I'm using stock kernel and 3.3 build was working fine except for Bluetooth and rotation which is not a big issue for me
[Miscellaneous Android Development] ildar_prophet:
wow! Behold the long awaited ROM!

Is it CM or something custom stock-based?
[Miscellaneous Android Development] anonimo95:
so we can have 4.2.2 on pipo s3? :laugh:

Guys, do you know if any of these roms work with Cube U9GT3?

Thanks
[Miscellaneous Android Development] Oma7144:
Gents,

Release of first Test Build Android 4.2.2 on rk30board ;)

http://crewrktablets.arctablet.com/?p=784

It is a bit tricky, so please only for experienced users:

- first boot will be with 3.0.36+ Kernel, which doesn't have touch-support

- after first full boot it is necessary to reflash 3.0.8+ Kernel

Let me have your feedback.

Hints:

- use app Density Changer (do not update) to set dpi=160

- disable automatical app-updates in Google Play settings

- use app Kernel Tuner to set CPU to 1.608 MHz

- use app Kernel Tuner to set SD Card cache size to 2.048

- use app Multiple User Enabler to enable Multi-User

- Oma -
[Miscellaneous Android Development] Chipsybg:
Can you please confirm if this will work on Cube U9GT3?

I tried the CM and the your build with the 3.0.8 kernel for the Cube, but it's not booting past the CWM.

I tried the fixes and the NAND wipes, but ti's not booting.

Any help?
[Miscellaneous Android Development] myvisione:
Will this also work on the Pipo U1Pro?

What shall I test?
[Miscellaneous Android Development] Oma7144:
Flash the pack as it is. When the tab boots flash the U1Pro kernel: http://crewrktablets.arctablet.com/?wpfb_dl=586

Could you please provide detailed instructions what to flash first (which tool)? (Is this format_NAND_fix) also needed for the Pipo?
[Miscellaneous Android Development] Oma7144:
There are detailed instructions in the download-pack. Please consider specific key for your tab.

Gents,

About 300 downloads and no feedback ...

... anyway, second Test Beta Build release Android 4.2.2 on rk30board will come with:

http://crewrktablets.arctablet.com/?p=784

- default 160 dpi

- default multi-user

- hide task-bar

- Ethernet support

- Hotspot support

- Init.d support

- USB-Hub enable

- Gamepad (PS2, XBox, ...)

- Kernel modules (cifs, tun, lan, serial)

- external SD mounted as NAND (up to 64 GB)

[Miscellaneous Android Development] ildar_prophet:
1st feedback :)

1. "EraseIDB" in the Instructions.txt was a killer-feature. I though I'd have my eMMC safe (NAND layout didn't change). :( Is it really necessary?

2. CMW is "awesome" failing to see the NAND. Maybe it's worth having two recoveries along with two kernels?

3. PIPO S3 users: bad news - couldn't get wifi working. The module 8192cu.ko.3.0.8+ should fit, but:

3a. Oma's custom kernel:

3b. stock kernel:

If insmod-ing manually it works (with PIPO's stock kernel. Is it possible to get rid of the `if2name'-parameter (at least?).

Please help!
[Miscellaneous Android Development] ildar_prophet:
So you don't see colors on the screen, even during the boot. And the bootsplash is also B&W, right? Then you seem to have the hardware problem.
[Miscellaneous Android Development] dodjob:
Hi there :)

I've inherited of a SINA-1 tablet. it's a clone of the captiva pad 10 someone mentioned on the page 17 I think.

You made him a kernel aaaaand I downloaded it. I flashed it with rkflashkit (I'm a linux *****) and well.. it went wrong ^^ somehow.

I'm pretty n00b concerning the RKworld and I think I might have made something very wrong.

The tablet was "bricked" and after a reboot in recovery and a reflash of the old one (I HAVE DUMPED IT!)

I could reboot the tablet correctly.

SO

Did I made something wrong?

Also here is the "I found you" log of my Rkflashkit:

I would really like to have a CM on this tablet. I would be honest, even if the kernel is stock, is it possible to just flash a system for RK3066 with a stock kernel?

Also, please don't burn me. but I have only 1gig of place for my apps. Is tehre a way to increase this?

The Grüß,

H.
[Miscellaneous Android Development] wuith:
What version is the stock kernel of your tablet?

If it is 3.0.8+ probably you can install CM10.1 for rk3066. Search in crewrktablets. Just change the kernel.img from that ROM for the stock one of your tablet.

If it is 3.0.36+ you can install 4.2.2 AOSP version or CM11 from rk3188 in the same way (untick loader!)

If you are lucky everything (wifi!) will work without any patch.

For changing the space for apps in Stock ROM you need to unpack the stock update.img and edit the parameter file. More info in google

Cheers!
[Miscellaneous Android Development] dodjob:
thanks!

Just to be sure :)

Do I have to use the the rktool to flash the complete rom after having replaced the kernel ind the folder or can i simply flash system and boot images?

regards,

H.
[Miscellaneous Android Development] wuith:
I have always flashed the whole ROM and with the program that comes when you download the ROM and following any note that is standing there (f.e. In a rk3188 ROM is standing something like "For rk3066 with 3.0.36+ untick loader").

Maybe somebody with more knowledge could answer you better but I guess that it is not possible to just flash some partitions (system and boot) going from one ROM to another (or even in an update) because the size of the partitions might be different or could even have the user and internal memory together. And mostly is necessary a factory reset before using. The MicroSD keeps however without problem.

Cheers
[Miscellaneous Android Development] ildar_prophet:
I strongly advice to repartition, including Erase IDB. Advantages:

Enough space in /data and other partitions

You may then flash any other ROM without repartition later (i.e. that would be your final repartition)

But beware: That will vanish your internal SDCARD which is on NAND you repartition.
[Miscellaneous Android Development] Oma7144:
Thank you for feedback!

The included homebrew kernel is for Odys Genio. So it only works for that tab. Kernel for Captiva Pad 10.1 is already in the archive: http://crewrktablets.arctablet.com/?wpfb_dl=796. If your tab is somehow different pls upload the dumped kernel for the archive.

Hi oma :)

Yeah the captiva's kernel does not work for me :/ I get a grey/black dimmed screen at start (where the sina-1 logo normaly comes) and it stays there :/

Again, if I could get it to work, I would be really really happy ;)

Hello,can you please find the exact rom for that RK3066SDK Tab. There is no manufactering logo or name.

in settings>about>I can only remember......

model: RK3066sdk

Kernel: 3.0.6+

Please help :rolleyes:
[Miscellaneous Android Development] ildar_prophet:
As more I deal with china devices as much I understand they don't actually need any names.

But that doesn't mean you can't use Oma's ROMs on your tab. Just a few steps (my Best practice recommendations):

backup essential software pieces: kernel, ROM (kernel+boot.img+system+optional recovery). This is quite easy as devices are usually rooted.

Find buttons combination to get into FW flashing mode

Get as much device and stock ROM info as you can. This may help in case you have problems with a custom ROM

Some details on the points above:

pull out USB, turn off the device, holding a button push power, then release buttons. The screen should remain black, but if you connect USB to your computer, the PC should see a USB device

My blog post on the topic

After that you can try Oma's ROMs that should work fine in 90% of cases.
[Miscellaneous Android Development] marzan1978:
Thank you for suggestion.

Device CWM is working but not found any suitable rom for tht tab..tried 4-5 rom with different manufacturer bt not working...problems like half of the screen remain black or touch not working,boot loop etc... :(

If anyone recognise the given device then please suggest me the exact rom for that device. :confused:
[Miscellaneous Android Development] Oma7144:
I would say your chance has gone at the point you killed the genuine kernel by flashing whatever into the tab.

Hi there,

i got "Tablet Bitmore 1020" from Info Quest Greece... ofcourse there are no new firmwares with new versions of KitKat... just have 4.1.1 jelly bean

2.Flashing CM10.1 v1.4 build, kernel, boot, recovery (touch)

3.Format NAND with zip script..

4.Install model fix..

5.rebooting - works with no wifi. reboot / shutdown perfect..

seems bluetooth (not so sure-because not having any other bt device try it) works

seems sound is ok

2xcameras working

Have these problems...

may be you can help me if tell me any commands for adb shell..

NO WIFI

NO ROTATION OF SCREEN (when trying your sensor fixes, reboot and loops for ever crew rktablets)

+after sensor fixes... try to reflash it, install all fixes blablah... but animation of crew rktablers stills loops ! :( - only if i flash with original bitmore restores ok.. but then when i reflash the same still loops for ever crew rktablets :(

Thanks in advance..

not founding apps after restart... need to reinstall.. why ?

This will change only bluetooth driver ?? -> because the truth is that already moved and installed some apps.. to test it...

proper formatted NAND -> here what i am doing...

1)Flashing factory-firmware for Bitmore

2)erasing IDB, Flashing with kernel+cwm touch recovery...

3)Install from zip/sdcard... Format nand...

4)reboots...goes at CWM

5)Install Model Fix, sensor fix,reboots goes at CWM

6)Install mount ext_SD..reboots...shutdown...

7)Power on- waits... changing basic info/lang/wifi/enabling programmer mode/adb usb...checking already swapped memories int with ext ///shutdown

8)Power on-setup googleplay...installing app... plays... shutdown...

9)powen on.. all settings ok... but app... is not there...

After mount ext sd... wants run script format again ?

Is now possible if already installed apps to int_sd or at internal memory - to mount ext_sd... ?

Vielen Dank!

Now I went into the settings to activate Wifi an it rebootet after some seconds and now it reboots after it reaches the "desktop".

Porbably I have to flash a wifi "driver", but how can I find my wifi chip inside the tab?

It is the same like the Odys Titan, Study Tab, Ventos 8.0 (RK Edition).

And (before applying your fix) when pressing power button to acivate standby it reboots, too.

Stami

OK, I think it has the MT5931 and flashed http://crewrktablets.arctablet.com/?wpfb_dl=2697, but still reboots and then bootloop.

OK, I installed http://crewrktablets.arctablet.com/?wpfb_dl=2692 and Wifi works perfectly it is very mooth and fast.

What does not work is the screen rotation (in camera its wrong, too) and bluetooth can't be enabled.

How can I deactivate the telephone module (striked out SIM Card symbol), I use it only with wifi?

Another strange thing is that it looses the stored wifi after some time in standby/switched off display, after a reboot its back again or i have to enter the password again.

->happens at work where the WiFi is quite weak, at home no problem.

And Kodi does not start and sometimes it "soft" reboots. :(
